Key: PIG-564

Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.2.0
Reporter: Viraj Bhat
Assignee: Olga Natkovich
Attachments: PIG-564.patch
Consider the following Pig script which uses parameter substitution
{code}
%default qual '/user/viraj'
%default mydir 'mydir_myextraqual'
VISIT_LOGS = load '$qual/$mydir' as (a,b,c);
dump VISIT_LOGS;
{code}
If you run the script as:
==
java -cp pig.jar:${HADOOP_HOME}/conf/ -Dhod.server='' org.apache.pig.Main
-param mydir=mydir-myextraqual mypigparamsub.pig
==
You get the following error:

Also tried using: -param mydir='mydir\-myextraqual'
This behavior occurs if the parameter value contains characters such as +,=,
?.
A workaround for this behavior is using a param_file which contains
param_name=param_value on each line, with the param_value enclosed by
quotes. For example:
mydir='mydir-myextraqual' and then running the pig script as:
java -cp pig.jar:${HADOOP_HOME}/conf/ -Dhod.server='' org.apache.pig.Main
-param_file myparamfile mypigparamsub.pig
The following issues need to be fixed:
1) In -param option if parameter value contains special characters, it is
truncated
2) In param_file, if param_value contains a special characters, it should be
enclosed in quotes
3) If 2 is a known issue then it should be documented in
http://wiki.apache.org/pig/ParameterSubstitution

Olga Natkovich commented on PIG-564:
Thanks, Giri. I looked at warnings anf they are result of adding new test files
for parameter substitution that don't have apache license because they don't
support comments. So nothing to fix there.
I will be committing the patch later today.

Alan Gates commented on PIG-564:
Questions/comments on the patch.
1) Why did output1.pig change to look exactly like the new input5.pig? It
seems like output1.pig shouldn't have changed.
2) A comment in the javacc files on how OTHER and IDENTIFIER interact in the
pattern matching might be helpful, as it isn't immediately obvious (at least to
me :) ).
As long as 1 is ok, then +1.

Olga Natkovich commented on PIG-564:
Alan, thanks for review.
(1) output1.pig is a generated file. I think it was checked in initially by
mistake. Its content is irrelevant.
(2) I might have to resubmit a patch anyway if I figure out the extra warnings
(the link is broken at the moment). If I have to do that, I will also add
comments.

Viraj Bhat commented on PIG-564:
Another special character / is not handled correctly and is particularly
useful when passing nested output directories.
It is truncated when it is passed to Pig.
Example case:
{code}
a = load '/user/viraj/test1' using PigStorage(',') as (id1:int,
char1:chararray);
b = foreach a generate id1;

Now if we open the substituted Pig script (paramtest.pig.substituted).

Key: PIG-564
URL: https://issues.apache.org/jira/browse/PIG-564
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.2.0
Reporter: Viraj Bhat
Assignee: Olga Natkovich
Consider the following Pig script which uses parameter substitution
{code}
%default qual '/user/viraj'
%default mydir 'mydir_myextraqual'
VISIT_LOGS = load '$qual/$mydir' as (a,b,c);
dump VISIT_LOGS;
{code}
If you run the script as:
==
java -cp pig.jar:${HADOOP_HOME}/conf/ -Dhod.server='' org.apache.pig.Main
-param mydir=mydir-myextraqual mypigparamsub.pig
==
You get the following error:

Also tried using: -param mydir='mydir\-myextraqual'
This behavior occurs if the parameter value contains characters such as +,=,
?.
A workaround for this behavior is using a param_file which contains
param_name=param_value on each line, with the param_value enclosed by
quotes. For example:
mydir='mydir-myextraqual' and then running the pig script as:
java -cp pig.jar:${HADOOP_HOME}/conf/ -Dhod.server='' org.apache.pig.Main
-param_file myparamfile mypigparamsub.pig
The following issues need to be fixed:
1) In -param option if parameter value contains special characters, it is
truncated
2) In param_file, if param_value contains a special characters, it should be
enclosed in quotes

Period (.) is also a special character that seems to cause problems.

Another possible workaround seems to wrap the param between two ' or and
escape its beginning with a \
-param url='http://www.yahoo.com' -- http
-param url='\http://www.yahoo.com' -- http://www.yahoo.com
